The place is nice but I am just surprised that 1. Airbnb is actually not allowed in the building so stealth is required 2. The owner sent me a whole set of house rules offline which are not covered in the airbnb description. (Dont know whether this just applies for Chinese guest or for all). For example, one of the house rules is to restrict how many KWh of electricity we can use otherwise we will be charged extra. Although i am a responsible guest and are not likely to trigger any of the rules, I feel they should be these rules should be put in the house description for fairness and transparency.
